T480 - no sound, dummy output, Ubuntu 18.04

Hello. 

 

The soundcard on my t480 stopped working today, after the bios update from system update on ubuntu.

 

running 

lsmod | grep snd_hda_intel

returns

snd_hda_intel          40960  0
snd_hda_codec         126976  1 snd_hda_intel
snd_hda_core           81920  2 snd_hda_intel,snd_hda_codec
snd_pcm                98304  3 snd_hda_intel,snd_hda_codec,snd_hda_core
snd                    81920  9 snd_hda_intel,snd_hwdep,snd_seq,snd_hda_codec,snd_timer,thinkpad_acpi,snd_rawmidi,snd_seq_device,snd_pcm

when I run

lspci -nnk | grep -A2 Audio

I get no return.

 

when I check for the soundcard with

cat /proc/asound/cards

it returns no soundcard

jpfontenelle@Wallace:~$ cat /proc/asound/cards
--- no soundcards ---

I also already tried 

sudo alsa force-reload

with no success

 

I've browsed around the internet and I tried to install/purge/remove/reinstall but still no success

 

I even tried to create a bootable usb with ubuntu and boot from it, but still no sound.

 

Any suggestions?

 

Cheers

Hi,

I have the same problem.  Same notebook model and same Ubuntu version.

There is any workaround for this problem?

 

Thanks
